The rain starts at 11:04, exactly like always. Detective Mara Cole stands under the same broken awning across from the laundromat, pink neon flickering on the wet street. She has lived this hour forty times now. In sixty minutes, a man named Elias Voss dies in the apartment above. She has never saved him. Tonight she swears she will. The clock ticks. She steps off the curb.

Instead of saving Elias, Mara decides to catch the killer in the act. She slips into the alley behind the laundromat and waits in the shadows, gun drawn, watching the back stairs for whoever comes to do the deed.

A second cop, Reyes from her own precinct, slips up the stairs. Mara almost calls out, relieved. Then she sees the syringe in his gloved hand and the way he tests the door. Her own partner is the killer. She raises her gun.

Mara shoots Reyes in the leg before he reaches the door. He goes down cursing, syringe rolling away. She cuffs him to the stair rail. 'Why him?' she demands. Reyes laughs. 'Because Voss saw what you did, Mara. You just don't remember yet.' The clock reads 11:58.

'I saw nothing,' Mara snaps, but Reyes just grins from the rail. 'Voss filmed you, that first night. The bribe. The body you dumped. The loop's been hiding it for you.' The clock hits 11:59 and the memory floods back, all of it true. She sinks to the stairs as the lights die, finally knowing the killer was her all along. The rain starts again at 11:04.
